Possible to display one day (midnight to midnight) and data from different days

[falkio8]

I have done this in an Apex chart but would like to implement it with a plotly card. Until now I could not do anything like this tried with hours_to_show, period and offset.

I would like to display a fixed one day period and display the same entity but from different days to compare them. With apex its not a big deal but is it possible with plotly too?

Thanks!

Ok I think I found it in the config: hours_to_show: current_day
But is it possible to alter the "current_day" like in the example by some hours? e.g. starting at 4 o´clock?

yes, offset. Loving tip: rtfm :)

Thanks, I usually search before asking. So I didn´t found what I was looking for. What I don´t get is why the now marker is not down to y=0. My current solution:

type: custom:plotly-graph
title: BKW Leistung Vergleich
hours_to_show: 18
time_offset: |-
  $ex {
    const ms_to_show = get('hours_to_show') * 60 * 60 * 1000;
    const start_hour_utc = 4;
    const now = Date.now();
    const now_utc = now - new Date().getTimezoneOffset() * 60 * 1000;
    const start_of_day_utc = new Date(now_utc);
    start_of_day_utc.setUTCHours(start_hour_utc, 0, 0, 0);
    const start_time = start_of_day_utc.getTime();
    const elapsed = (now_utc - start_time + ms_to_show) % ms_to_show;
    const offset = ms_to_show - elapsed;
    return offset + 'ms';
  }
entities:
  - entity: sensor.wechselrichter_ac_leistung_2
    time_offset: 2d
    name: Vorgestern
  - entity: sensor.wechselrichter_ac_leistung_2
    time_offset: 1d
    name: Gestern
  - entity: sensor.wechselrichter_ac_leistung_2
    name: Heute
    line:
      width: 2
      color: red
  - entity: ""
    name: Now
    yaxis: y9
    showlegend: false
    line:
      width: 1
      dash: dot
      color: red
    x: $ex [Date.now(), Date.now()]
    "y":
      - 0
      - 1
refresh_interval: 10
layout:
  xaxis:
    dtick: 14400000
  yaxis:
    type: number
    range:
      - 0
      - 1000
```

That's because the now line is on axis y9.
Either put it in y1 (yaxis: y), or also set the y range of y9 in the layout
